Calibrachoa plant named ‘Balcabooni’

ABSTRACT

A new and distinct cultivar of Calibrachoa plant named ‘Balcabooni’, characterized by red-purple colored flowers having a black-colored center with an irregular central yellow-colored star pattern; medium green-colored foliage, and moderately vigorous, mounded-trailing growth habit, is disclosed.

Latin name of genus and species of plant claimed: Calibrachoa x hybrida.

Variety denomination: ‘Balcabooni’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant botanically known as Calibrachoa x hybrida and hereinafter referred to by the cultivar name ‘Balcabooni’.

The new cultivar originated in a controlled breeding program in Arroyo Grande, Calif. during March 2016. The objective of the breeding program was the development of Calibrachoa cultivars with attractive flower coloration, and a moderately vigorous, mounded-trailing growth habit.

The new Calibrachoa cultivar is the result of cross-pollination. The female (seed) parent of the proprietary Calibrachoa x hybrid breeding selection coded 13895-2, not patented, characterized by its dark cherry-red colored flowers having a central yellow-colored star pattern, medium green-colored foliage, low growth vigor and a compact-mounded growth habit. The male (pollen) parent of the new cultivar is the proprietary Calibrachoa x hybrida breeding selection coded 13504-2, not patented, characterized by its medium cherry-red colored flowers having a black-colored center with a central yellow-colored star pattern, medium green-colored foliage, and moderately vigorous, mounded growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during August 2016 in a controlled environment in Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since August 2016 in Arroyo Grande, Calif. and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balcabooni’ as a new and distinct cultivar of Calibrachoa plant:

-   -   1. Red-purple colored flowers having a black-colored center with         an irregular central yellow-colored star pattern;     -   2. Medium green-colored foliage; and     -   3. Moderately vigorous, mounded-trailing growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in having a flower color of a different shade of red-purple with a black-colored center and a more vigorous growth habit. Plants of the new cultivar differ from plants of the male parent primarily in having a flower color of a different shade of red-purple.

Of the many commercially available Calibrachoa cultivars, the most similar in comparison to the new cultivar is CAN-CAN Bumble Bee Pink ‘Balcanumbi’, U.S. Plant Pat. No. 29,547. However, in side-by-side comparisons, plants of the new cultivar differ from plants of ‘Balcanumbi’ in at least the following characteristics:

-   -   1. Plants of the new cultivar have a darker colored flower         throat area than plants of ‘Balcanumbi’.;     -   2. Plants of the new cultivar have smaller diameter corollas         than plants of ‘Balcanumbi’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs may differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balcabooni’. The plants were approximately 8 months old and grown in 3-gallon containers in an outdoor nursery environment in West Chicago, Ill. for approximately 5 months. Treatments are described below in the Detailed Botanical Description.

FIG. 2 illustrates a close-up view of an individual flower of ‘Balcabooni’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined in October 2018 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock under conditions comparable to those used in commercial practice. The plants were approximately 8 months old and grown in 3-gallon containers in an outdoor nursery environment in West Chicago, Ill. for approximately 5 months. Plants were given two pinches, the first at 3 weeks after cuttings were stuck and a second approximately 3 weeks later. Plants were treated with plant growth regulators of Daminozide at 2500 ppm and Chlormequat chloride at 750 ppm approximately 4 weeks after cuttings were stuck. Measurements and numerical values represent averages of typical plants.
